4.4.4. Configuring the pH setpoint
The pH setpoint configuration determines the time when acid is added to the system to reduce the water's pH. The
default value of the pH setpoint is 7.2.
To determine the value of the setpoint to be configured, refer to Taylor's balance, see § "3.1 I Balance the water".

4.4.6. Configuring the ORP setpoint
The ORP setpoint configuration determines the time at which chlorine is produced by the appliance. The level of
free chlorine must be controlled at regular intervals after initial installation. The default value of the ORP setpoint is
700 mV.
The value of the setpoint depends on the pool's environment, its affluence, and the amount of stabiliser present in the
pool water.
